This invention relates to Van improvement in shoe forms and more particularly to such forms of the type which comprise an eXpansible toe form and a back part wire.

The primary object of this invention resides in the manner of mounting the back part wire upon the crossbrace of the toe form, such brace being laminated preferably in three layers, and having a.' sliding'engagement with the toe form wall so that'when located in a shoe the back part wire exerts pressure upon the crossbrace and expands the toe form to lill or plump out the shoe.

Other objects Ywill appear from an eX- amination of the following description and of the drawing which lforms a part thereof and in which: Y

Fig. 1 is a side elevation with parts broken away illustrating one embodiment of this invention in the operative position;

Fig. 2 is a bottom plan view of the toe *forml shown in Fig. 1 in the inoperative position;

Fig. 3 is a sectional view taken along the line 3-3 of Fig. 1 illustrating the manner in which the back part wire is positioned in the crossbrace;

Fig. 4 is an enlarged sectional view taken along the line 4-4 of Fig. 2 illustrating the relation of the back part wire and crossbrace; and

Figs. 5 and 6 are enlarged sectional views illustrating other ways of attaching the back part Wire to the crossbrace.

The shoe form selected to illustrate this part wire 12. The toe form 11 is hollow and of Celluloid or other resilient material having a coned body portion 15 which terminates in ball anges 16 and 17 integrally connected by a tip flange 18. Pivotally secured at one end by an eyelet 19 or other suitable means to the flange 16 is a crossbrace 20, the other end of which carries a pin 21 which enters an arcuate slot 22 in the ange 1 The crossbrace is laminated having ,outer layers 23 and 24 and an intermediate layer 25, such layers being preferably though not necessarily of Celluloid or like material. The outer layers extend above and below the sonar 1931. seria No. 545,763.

flanges 16 vand 17 and the intermediate layer mounted between the flanges is preferably of equal thickness therewith. p

The back part wire 12 here shown consists of a relatively stiff wire rod covered by a tube of Celluloid 31 and is formed at its rear end with a loop 32 which, vas indicated in Fig. 1, bears against the heelfcounter 33 of a w rlhe forward end of the back partv wireA 12 is connected to the crossbrace by passing the end of the rod 30 thro-ugh the hole 38, the section 34 ofthe rod resting in the portion 36 of the slot and the tip 35 resting in the portion `37 ofthe slot. The section 34 of the rod acts as a fulcrum to permit a rocking movement of the back part wire within the limits defined by the Contact of the tip 35 with the layers 23 and 24.

The forward end of the back part wire may be connected to the crossbrace by means of an eyelet passed through the layers of the crossbrace and engaged at the shank by a loop formed at the forward end of the rod (see Figs. 5 and 6). In Fig. 5 the loop 40 at the forward end of the rod 30 rests upon the upper layer 23 and surrounds the shank of an eyelet 41. In Fig. 6 the loop 45 of the rod 30 enters a Vslot 46 formed in the intermediate layer 25 of the'crossbrace and surrounds the shank of an eyelet 47. While the connections shown in Figs. 5 and 6 permit a relative pivotal vmovement between the wire and crossbrace that pivotal movement is at right angles to that provided in the rst em-A bodiment the back part wire is of such length and. resiliency that'it can be bent easily when the form is inserted in a shoe.

Thus the insertion of the shoe form into a shoe results in the yieldable advance of the Cil another position contracts the toe form, anda bacl: part wire secured at its forward endl to the crossbrace, said crossbrace being lammated and said back` part wire being pivotallyconnected to one lamination of the crossbrace.

2.A shoe form comprising an expansible toe form having a pivotally mounted crossbrace which in one position expands and in another position contracts the toe form, and

` a back part Wire secured at its forward end to the crossbrace, said crossbrace being laminated with at least three layers, the interme diate layer having a slot therein which reeeives the end of the back part wire.

3. A shoe form comprising an expansible toe form having a pivotally mounted crossbrace which in one position expands and in another position contracts the toe form, and a back part wire secured at Aits forwardend to the crossbrace, said crossbrace being laminated with at least three layers, the inter- Y mediate layer having a slot therein and one outer layer having a hole leading to said slot, the slot and hole receiving the end of the back part Wire.

4. A shoe form comprising an expansible toe form having a pivotally mounted crossbraoe which in one position expands and in another position contracts the toe form, and a back part Wire securedat its forward end tothe orossbrace, said erossb-race being laminated, one layer having a slot'therein and another layer having a hole leading to the slot, the slot and hole coacting to receive the forward end of the back part wire.

5. A shoe form comprising an expansible toe form having a pivotally mounted crossbrace which in one position expands and in another positionV contracts the Ltoe form, and a back part wire secured at its forward end to the crossbrace, said crossbrace being laminated, one layer having a slot therein comprising alongitudinally extending portion and a transversely extending portion and anotherv layer having a hole leading to the longitudinally extending portion of the slot, both portions of the slot and the hole receiving the forward end of the back part wire.

6. A toe form comprising'a body portion having ball flanges and a laminated crossbrace connecting saidy flanges and comprising at least three layers, one end of each of Vthe outer layers vbeing pivotally connected to one of said flanges and the other end of each outer layer having a slidable connect-ion with the other flange andthe intermediate layer being between the flanges and having substantially the thickness thereof.

7. A toe vform comprising a body portion having yball flanges and a laminated crossbrace connecting said flanges and comprising at least three layers, the ends of the outer layers extending respectively above and below the flanges, one end being pivotally secured to a flange and the other end having a slidable engagement with the other flange and the intermediate layer being between the flanges and having substantially the thickness thereof. y

8. A toe form comprising a body portion having ball flanges, one at least of which has an arcuate slot therein, and a laminated crossbrace connecting saidv flangesl and comprising kat least three layers, the ends of the outer layers extending respectively above and below the flanges, one end of the crossbrace being pivotally secured to one of said flanges, a pin which passes through the arcuate slot and joins the ends of the outer layers, and the intermediate layer ybeing between the flanges and having substantially the thickness thereof. n f
